TABLE  II. 


SUNRISE  AND  SUNSET  FOR  SOUTHERN  LATITUDES,  1917. 

In  the  case  of  a  southern  latitude  the  time  of  sunrise  or  sunset  is  taken  from  Table  I,  with 
the  corresponding  northern  latitude,  not  for  the  given  date  but  for  a  date  about  six  months  earlier 
or  later,  which  is  to  be  found  in  the  following  table.  The  time  taken  from  Table  I,  whether  of 
sunrise  or  sunset,  must  be  corrected  by  the  quantity  given  in  Table  II  on  the  same  line  with  the 
given  date. 

Example. — May  10, 1917,  civil  date,  in  latitude  -38°,  required  the  time  of  sunrise  and  sunset. 

The  astronomical  date  is  May  9  for  sunrise  and  May  10  for  sunset;  Table  II  gives  November 
11  and  12  as  the  corresponding  dates,  northern  latitude,  while  the  correction  is  +12m  in  each  case.

42  MOONRISE  AND  MOONSET,  1917. 

FOR  NORTHERN  STATIONS  NOT  ON  THE  MERIDIAN  OF  GREENWICH,  AND  FOR 

SOUTHERN   STATIONS. 

For  northern  stations  not  on  the  meridian  of  Greenwich. — For  longitudes  twelve  hours  or  less 
west  from  Greenwich,  obtain  the  data  for  the  given  latitude  from  Table  III  for  the  given  date 
and  for  the  date  following;  for  longitudes  twelve  hours  or  less  east  from  Greenwich,  obtain  the 
data  for  the  given  latitude  from  Table  III  for  the  given  date  and  for  the  date  preceding.  Subtract 
the  time  on  the  earlier  date  from  the  time  on  the  later  and  multiply  the  difference  by  the  twenty- 
fourth  part  of  the  longitude  in  hours  and  decimals  of  an  hour,  positive  if  west,  negative  if  east. 
Apply  the  product  as  a  correction  to  the  time  on  the  given  date. 

For  southern  stations. — The  instant  of  moonrise  or  moonset  for  any  station  south  of  the  equator 
is  that  of  moonset  or  moonrise,  respectively,  at  a  place  of  the  same  latitude  north  of  the  equator 
whose  longitude  is  twelve  hours  different  from  that  of  the  southern  station. 

If  the  southern  station  be  twelve  hours  or  less  west  from  Greenwich  and  the  phenomenon  at 
that  station  occurs  between  noon  and  midnight,  the  local  astronomical  day  will  be  the  same 
at  the  southern  and  northern  stations.  If,  however,  the  phenomenon  at  the  southern  station 
occurs  between  midnight  and  noon,  the  local  astronomical  day  at  the  northern  station  will  be  one 
day  later  than  at  the  southern. 

If  the  southern  station  be  twelve  hours  or  less  east  from  Greenwich  and  the  phenomenon  at 
that  station  occurs  between  noon  and  midnight,  the  local  astronomical  day  at  the  northern  station 
will  be  one  less  than  at  the  southern  station.  If,  however,  the  phenomenon  occurs  between  mid- 
night and  noon,  the  local  astronomical  day  will  be  the  same  at  the  two  stations. 

Having  thus  determined  the  true  astronomical  day  at  the  northern  station,  compute  by  the 
rule  for  northern  latitudes.  For  the  desired  local  time  of  moonrise  at  the  southern  station  change 
the  time  of  moonset  at  the  northern  station  twelve  hours.  For  the  desired  local  time  of  moonset 
at  the  southern  station  change  the  time  of  moonrise  at  the  northern  station  twelve  hours. 

Example. — December  10, 1917,  civil  date,  find  the  time  of  moonrise  and  moonset  in  longitude 
4h  43m  west  from  Greenwich  and  in  latitude  33°  3(X  south. 

The  longitude  of  the  northern  station  is  7h.3  east  from  Greenwich  and  its  latitude  is  33°. 5  N. 
Upon  inspection  of  Table  III  it  is  seen  that  the  astronomical  day  at  the  southern  station  is  Decem- 
ber 9  for  moonrise  and  December  10  for  moonset,  the  former  phenomenon  occurring  between 
midnight  and  noon,  the  latter  between  noon  and  midnight.  For  the  northern  station,  in  accord- 
ance with  the  precepts  given  above,  both  phenomena  are  to  be  computed  for  December  10. 

At  northern  station— 

Moonrise.  Moonset.

TABLE  IV. 


LOCAL  ASTRONOMICAL  MEAN  TIME  OF  SUNRISE,  MERIDIAN  OF  GREENWICH,  1918. 

To  obtain  civil  time,  subtract  12  hours,  mark  the  result  A.  M.,  and  add  one  to  the  day. 

To  obtain  the  standard  time  at  any  station,  increase  the  local  time  by  the  number  of  minutes 
the  station  is  west  of  the  standard  meridian,  or  decrease  the  local  time  by  the  number  of  minutes 
the  station  is  east  of  the  standard  meridian. 

For  sunrise  in  southern  latitudes  see  page  60.

the  station  is  west  of  the  standard  meridian,  or  decrease  the  local  time  by  the  number  of  minutes 
the  station  is  east  of  the  standard  meridian. 

For  sunrise  in  southern  latitudes  see  page  60.

TABLE  V. 


SUNRISE  AND   SUNSET  FOR  SOUTHERN  LATITUDES,  1918. 

In  the  case  of  a  southern  latitude  the  time  of  sunrise  or  sunset  is  taken  from  Table  IV,  with 
the  corresponding  northern  latitude,  not  for  the  given  date  but  for  a  date  about  six  months  earlier 
or  later,  which  is  to  be  found  in  the  following  table.  The  time  taken  from  Table  IV,  whether  of 
sunrise  or  of  sunset,  must  be  corrected  by  the  quantity  given  in  Table  V  on  the  same  line  with  the 
given  date. 

Example. — May  10,  1918,  civil  date,  in  latitude  -38°,  required  the  time  of  sunrise  and  sunset. 

The  astronomical  date  is  May  9  for  sunrise  and  May  10  for  sunset;  Table  V  gives  November 
11  and  12  as  the  corresponding  dates,  northern  latitude,  while  the  correction  is  +12m  in  each  case.

For  northern  stations  not  on  the  meridian  of  Greenwich. — For  longitudes  twelve  hours  or  less 
west  from  Greenwich,  obtain  the  data  for  the  given  latitude  from  Table  VI  for  the  given  date 
and  for  the  date  following;  for  longitudes  twelve  hours  or  less  east  from  Greenwich,  obtain  the 
data  for  the  given  latitude  from  Table  VI  for  the  given  date  and  for  the  date  preceding.  Subtract 
the  time  on  the  earlier  date  from  the  time  on  the  later  and  multiply  the  difference  by  the  twenty- 
fourth  part  of  the  longitude  in  hours  and  decimals  of  an  hour,  positive  if  west,  negative  if  east. 
Apply  the  product  as  a  correction  to  the  time  on  the  given  date. 

For  soutfiern  stations. — The  instant  of  moonrise  or  moonset  for  any  station  south  of  the  equator 
is  that  of  moonset  or  moonrise,  respectively,  at  a  place  of  the  same  latitude  north  of  the  equator 
whose  longitude  is  twelve  hours  different  from  that  of  the  southern  station. 

If  the  southern  station  be  twelve  hours  or  less  west  from  Greenwich,  and  the  phenomenon  at 
that  station  occurs  between  noon  and  midnight,  the  local  astronomical  day  will  be  the  same 
at  the  southern  and  northern  stations.  If,  however,  the  phenomenon  at  the  southern  station 
occurs  between  midnight  and  noon,  the  local  astronomical  day  at  the  northern  station  will  be  one 
day  later  than  at  the  southern. 

If  the  southern  station  be  twelve  hours  or  less  east  from  Greenwich  and  the  phenomenon  at 
that  station  occurs  between  noon  and  midnight,  the  local  astronomical  day  at  the  northern  station 
will  be  one  less  than  at  the  southern  station.  If,  however,  the  phenomenon  occurs  between  mid- 
night and  noon,  the  local  astronomical  day  will  be  the  same  at  the  two  stations. 

Having  thus  determined  the  true  astronomical  day  at  the  northern  station,  compute  by  the 
rule  for  northern  latitudes.  For  the  desired  local  time  of  moonrise  at  the  southern  station  change 
the  time  of  moonset  at  the  northern  station  twelve  hours.  For  the  desired  local  time  of  moonset 
at  the  southern  station  change  the  time  of  moonrise  at  the  northern  station  twelve  hours. 

Example. — December  20,  1918,  civil  date,  find  the  time  of  moonrise  and  moonset  in  longitude 
4h  43m  west  from  Greenwich  and  in  latitude  33°  307  south. 

The  longitude  of  the  northern  station  is  7h.3  east  from  Greenwich  and  its  latitude  is  33°. 5  N. 
Upon  inspection  of  Table  VI  it  is  seen  that  the  astronomical  day  at  the  southern  station  is  December 
20  for  moonrise  and  December  19  for  moonset,  the  former  phenomenon  occurring  between  noon 
and  midnight,  the  latter  between  midnight  and  noon.  For  the  northern  station,  in  accordance 
with  the  precepts  given  above,  both  phenomena  are  to  be  computed  for  December  20.
